👋 Hello there, I'm Grimmer Kang 
I'm passionate to make something good for people. Love science, programming, psychology, but not limited to these. Participated IoT, Streaming, Astronomy, AI, and Medical-imaging (partial in work and side projects) domains. Use JavaScript/TypeScript/Python and used C/C++/C#/Objective-C and Go (side project) languages. I've been a manager or a leader to build mobile-app and full-stack teams successfully and introduced Agile culture/flow in those organizations. Welcome any collaboration.
